OK, backing up your logical logs to disk (vs. tape) seems a little cross-purpose,
but if you want to back up your logical logs, don't have a tape drive, and copy the logs
to a physical disk other then where the logs live, this might be one way to do it.

One might notice there is no restore process documented here. That still needs to be written and tested.

First, create a 'named pipe' to simulate a tape drive to write to.
Name it 'logbackup.pipe'.

What is a 'named pipe' ???, you ask...

A named pipe is a special file that is used to transfer data
between unrelated processes. One (or more) processes write to it, while
another process reads from it. Named pipes are visible in the file
system and may be viewed with `ls' like any other file. (Named
pipes are also called fifos; this term stands for `First In, First
Out'.)

Named pipes may be used to pass data between unrelated processes, while
normal (unnamed) pipes usually only connect parent/child processes.
Named pipes are strictly unidirectional, even on systems where anonymous
pipes are bidirectional (full-duplex).

How do I create a named pipe?

To create a named pipe interactively, you'll use either mknod or mkfifo.
